K20A2 EG Pinging

[K20EG]

I have a K20A2 EG with K-PRO. I'm running the Stock RSX with Cold air program from Kmanager. The car runs fine and ildes fine, but except that it pings under 1/4 throttle. I have the full size Koyo radiator with a fan. I'm thinking maybe it's because I'm not getting enough cool air into the engine bay and the motor is running hot. I haven't been able to datalog while driving because my laptop has a worn out battery and it wouldn't last 5 minutes without being plugged to the wall. Please help.
